Welcome to Umbrello - The UML Modeller

Umbrello UML Modeller is a Unified Modelling Language (UML) diagram program based on KDE Technology.

UML allows you to create diagrams of software and other systems in a standard format to document or design the structure of your programs.

You may take a look at the screenshots to see umbrello in action.

Our handbook gives a good introduction to Umbrello and UML modelling.

Umbrello comes with KDE SC, included with every Linux distribution and available through your package manager. See Installation to install Umbrello.
